Role of environmental heterogeneity in structuring the macrobenthic community in a tropical sandy beach, west coast of India
(Springer, 2012)In most ecosystems, community structure emerges as a result of the complex interaction between biotic and environmental variables. Sandy beaches connected to adjacent ecosystem like estuaries/creeks provide an opportunity ... -
Seasonal variability of the vertical fluxes of Globigerina bulloides (D'Orbigny) in the northern Indian Ocean
(University of Hamburg, 1996)Settling particles intercepted using time-series sediment traps at seven locations in the northern Indian Ocean have been examined for the spatial and temporal variability in the distribution and fluxes of Globigerina ... -

Sediment dispersal in the macro tidal Gulf of Kachchh, India
(NIO, Dona Paula, Goa (India), 2000)Studies of sub-bottom physiography, tidal parameters and characteristics of the sediment in the Gulf of Kachchh have been made. The tidal range becomes progressively higher in the inner gulf with associated high magnitude ... -
Sediment Oxygen Demand in Cochin backwaters, a tropical estuarine system in the south-west coast of India
(Elsevier, 2012)Eutrophication has often been one of the major problems encountered in estuaries and coastal waters. The oxic/anoxic status of an estuary can be effectively determined by measurement of the Sediment Oxygen Demand (SOD). ... -
Spatial and temporal variability of the heat budget parameters and currents in the coastal waters of Visakhapatnam, east coast of India
(NISCAIR, CSIR, 1995)Analysis of the thermal structure in coastal waters off Visakhapatnam revealed sub-surface inversions during October. In postmonsoon, a good association existed between wind stress (tau) and total heat loss (Qe+Qs) and ... -
Spatial and temporal variations of carbonate content in the beach and nearshore environments off Goa, west coast of India
(NISCAIR, New Delhi, 1993)Sediment samples collected from dunes, beaches (Calangute, Baina and Colva) and nearshore environments along the coast of Goa, have been analysed for their carbonate content. The results show the presence of very high ... -
Spatio-temporal variations in biochemical composition, condition index and percentage edibility of the clam, Paphia malabarica (Chemnitz) from estuarine regions of Goa
(CSIR-NISCAIR, 2013)Biochemical compositions, condition index (CI) and percentage edibility (PE) of an estuarine clam, Paphia malabarica, were studied from two estuarine regions of Goa during March 2009 to March 2010. Relationships between ... -
Spatiotemporal variability in archaeal communities of tropical coastal waters
(Springer, 2013)Spatiotemporal variations in the archaeal community structure from four locations along the central west coast of India were analyzed by denaturing gradient gel electrophoresis (DGGE) profiling and sequencing of prominent ... -
sup(234) Th scavenging and particle export fluxes from the upper 100 m of the Arabian Sea
(Current Science Association, Bangalore, India, 1996)We have determined the particle scavenging rates, export fluxes of sup(234) Th and settling particles from the upper 100 m of the Arabian Sea as a part of the JGOFS (India) Programme. The spatial and temporal measurements ... -
Temporal and ephemeral variations in copepod community in the estuaries of Mandovi and Zuari - west coast of India
(Cambridge Univ. Press, UK, 2001)In the tidal-dominated coastal plain estuaries, the magnitude of temporal and ephemeral variations in the abundance of the calonoid copepod community was evaluated over two annual cycles by two-way ANOVA. The species by ... -
Temporal and spatial variability of trace metals in suspended matter of the Mandovi estuary, central west coast of India
(Springer, 2012)Studies on the suspended particulate matter (SPM) in the Mandovi estuary, western India indicate that during the monsoon and pre-monsoon, the SPM increases, and the major and trace metals decrease from stations in the ... -
Temporal and spatial variations in hydrographic conditions of Mandovi estuary
(CSIR-NISCAIR, 1975)Nine stations over a stretch of 21 km of Periyar river estuary were sampled during January to December 1981. Particulate matter varied from 3-253 mg.1 super(1) at the surface and 24.8-257mg.1 super(1) at the bottom. ... -
Temporal and spatial variations in particulate matter, particulate organic carbon and attenuation coefficient in Cochin Backwaters
(CSIR-NISCAIR, 1989)Nine stations over a stretch of 21 km of Periyar river estuary were sampled during January to December 1981. Particulate matter varied from 3-253 mg.1 super(1) at the surface and 24.8-257mg.1 super(1) at the bottom. ... -
Temporal variation of diatom benthic propagules in a monsoon-influenced tropical estuary
(Elsevier, 2008)Temporal variations in the diatom benthic propagule (DBP) community and their role in the phytoplankton community in a monsoon-affected tropical estuary, Zuari estuary, Goa (India) are presented. The DBP from the sediments ... -
Temporal variations in dimethylsulphoniopropionate and dimethyl sulphide in the Zuari estuary, Goa (India)
(Elsevier, 2003)Despite tropical estuarine systems representing important sites for active biogeochemical processes, studies on dimethyl sulphide (DMS) in these systems are sparse. Here we report on DMS and dimethylsulphoniopropionate ... -
The Arabian Sea: Physical environment, zooplankton and myctophid abundance
(Council of Scientific and Industrial Research, New Delhi, 1999)The Arabian Sea is one of the most productive regions of the world oceans. This productivity mainly results from coastal and open ocean upwelling in summer and cooling effects during winter. Earlier and more recent studies ... -
Time and space variations of monsoonal upwelling along the west and east coasts of India
(Pergamon, 1999)The study of monthly mean local temperature anomaley (LTA defined as the difference between coastal and mid-ocean sea surface temperature), and Ekman transport along the west and east coasts of India based on 60-year data ... -
Variation in meroplankton along 78 degrees E Meridian
